I have two Netgear Wi-Fi routers in my house in order to get coverage everywehre (actually one in the garage/office and one in the house). Both are on the most up to date version of firmware etc.. and I have no probs connecting to either of them from laptops or my wife's iphone.

However, my blackberry only connects fully with one of them. With the other - it says on the home screen its connected, but I only get the greyed out Wi-Fi logo - which I believe means it doesn't have full blackberry connectivity and blackberry data isn't going via wi-fi?

Does anyone have any suggestions as to why this might be happening? any suggestions on any config changes I should experiment with on the problematic wi-fi router?

I got a similar problem.
I do connect to WIFI Belkin router but, when I run the internet browser -while running the 3G- I get disconnected from the WIFI. I then try to reconnect the WIFI, I get a canít not acquire the IP address message.
A dumb question: is the Pre-Shared Key (PSK) the same as the router password? Sorry for sounding so basic.
